Extruded ALUMINUM profile
First, design and manufacture a mold according to the profile product section, and use an extruder to extrude the heated round cast rod from the mold. The commonly used grade of 6063 alloy also uses an air-cooling quenching process and subsequent artificial aging process during extrusion to complete the heat treatment strengthening. Different grades of heat-treatable and strengthened alloys have different heat treatment systems.
Coloring (I will focus on the oxidation process first)
Oxidation: The extruded aluminum alloy profile has a weak surface corrosion resistance, and it must be surface treated by anodizing to increase the corrosion resistance, wear resistance and appearance of the aluminum.
The main process is:
(1) Surface pretreatment: Use chemical or physical methods to clean the surface of the profile and expose the pure matrix to facilitate obtaining a complete and dense artificial oxide film. It is also possible to obtain a mirror or matte (matt) surface by mechanical means.
(2) Anodizing: The surface pretreatment of the profile will undergo anodization on the surface of the substrate under certain process conditions to form a dense, porous, and strong adsorption Al2O3 film.
(3) Sealing: sealing the pores of the porous oxide film formed after anodic oxidation to enhance the anti-pollution, corrosion resistance and wear resistance of the oxide film. The oxide film is colorless and transparent. Using the strong adsorption of the oxide film before sealing, some metal salts are adsorbed and deposited in the film pores, which can make the appearance of the profile show many colors other than the natural color (silver white), such as: black, bronze, Golden yellow and stainless steel color, etc.
Characteristics and properties of aluminum profiles after various surface treatment processes
Frosted fabric aluminum profile: Frosted aluminum profile avoids the shortcomings of bright aluminum alloy profiles that will cause light interference in certain environments and conditions in architectural decoration. Its surface is as delicate and soft as brocade, which is very popular in the market. However, the existing frosted materials must overcome the uneven surface sand and the lack of pattern patterns can be seen.
Multi-tone surface treatment aluminum profile: The monotonous silver white and brown color can no longer meet the good cooperation of architects with exterior wall decorative tiles and exterior wall latex. The new stainless steel color, champagne color, golden yellow, titanium gold, red series ( Wine red, maroon, black, purple), etc. plus colored glass can make the decorative effect icing on the cake. These profiles must be chemically or mechanically polished and then oxidized for the best results.
Electrophoretic painted aluminum profile: The surface of the electrophoretic painted profile is soft and can resist acid rain of cement and mortar. 90% of the aluminum profile in Japan is electrophoretic painted.
Powder electrostatic spraying aluminum profiles: Powder electrostatic spraying profiles are characterized by excellent corrosion resistance, acid, alkali and salt spray resistance are much better than oxidation colored profiles.
Plasma-enhanced electrochemical surface ceramicized aluminum profile: This type of profile is the most advanced processing technology in the world today. The quality of this profile product is good, but the cost is relatively high. It has more than 20 kinds of tones, and its biggest feature is that it can be colored like a printed cloth according to the needs. The surface of the profile is colorful and the decoration effect is excellent.
It can be divided into alloy grade aluminum profiles such as 1024, 2011, 6063, 6061, 6082, 7075, among which the 6 series is the most common. The difference between different grades is that the proportions of various metal components are different, except for the commonly used aluminum profiles for doors and windows For example, in addition to architectural aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series, industrial aluminum profiles do not have a clear model distinction, and most manufacturers process them according to the actual drawings of customers.
